VFLASH SOFTWARE
13.1 INTRODUCTION
VFLASH is TEKNOR's Flash EPROM transfer utility program designed for TEKNOR's
SBC. Its main function is to download DOS files to the Flash EPROM disk (also referred to
as data Flash).
A Flash EPROM disk created with VFLASH is very much like a hard disk. A partition is
created and data is stored in files, just like on a hard disk. The main difference between the
two is that this Flash disk is a read-only drive. Therefore, in order to write software to this
Flash disk, you must use the VFLASH Transfer Utility.
However, with the FLASH FILE SYSTEM II software from Microsoft, Flash EPROM disks
are read/write and may be accessed via DOS commands (this utility is covered Section 12).
Depending on your particular configuration, VFLASH may be used to transfer information to
a Flash disk by one of two modes:
1. Directly, from your local board hard disk or floppy drive to the local FLASH EPROM
disk.
2. Remotely, from a remote computer running the VFLASH program to a local FLASH
EPROM disk via a serial COM port (1 or 2).
When operating a serial download, the board must be initiated consequently using the W4
jumper. In this mode, the TEK-CPCI-1000 board is set to wait for signals from the remote
computer's VFLASH program.
The above sections explain how to run the program in interactive mode via menus. It is also
possible to run the program without menus by using a command that specifies options, and
files and parameters.
This mode is called batch mode and is described in Section 13.6.
